A Honey Badger. Get bit by a cobra, walk it off in a few hours. Anything else thinks you are a snack? They better think twice. Nothing f#@ks with a Honey Badger!!!

A dolphin, surf my life away.

I want to be a hot dog because I get to be a variety of animals.

I agree with Abbey, the turkey vulture.

I'd want to be a cat. They live a life o leisure, but best of all they can purr.

A bear as I can sleep through the horrible winter and stay awake stuffing my face all summer. bliss

A snowy owl because their world is mostly purple shadows and air, experienced on silent wings against a backdrop of glittering stars, and orange moons...and because they are not Republicans.

Orca or dolphin.

Smart, social, seem to enjoy life and inquisitive and curious.

Active life, no money hassles and don't seem to get sick too often.

You read my mind. I was thinking last night of posting this very question. Thanks for doing it and probably better phrased than I would have.
My choice would be the raven. They're very smart birds, as all corvus's seem to be from all the testing and observation that has been done on them. And best of all, they fly like aces. I've observed crows and ravens for many, many years under many circumstances, and I have to conclude that raven is who I'd prefer. I'm a bit ambivalent about crows, they can be real assholes. But both species are very intelligent and very social. So, yeah, raven (and they're bigger than crows).

I would want to be a rhinoceros, up high in the forest canopy leaping from tree to tree with the swiftness of a jackal and the grace of a swan. Of course I would be careful not to break anything or appear too showy. With respect to characteristics that appeal to me is that glorious horn!

A cat, without a doubt. Cats are very sensuous and independent, yet loving when they choose it. I definitely would not want to be a human again. We are a scourge on the planet.

Most definitely a dog.
They almost always seem to be happy even about doing simple things like going for a walk or playing frisbee in the backyard.
